My invention relates to drain construction, and more particularly tomeans for draining a depressed area such as a lagoon, swamp or portionofland on which water stands for a period during each year, theprincipal object of the invention being to provide a maX- imum ofdrainage elements in a minimum of space for eectively draining` a largearea without interfering with the tilling of the area. Further objectsof the invention are to provide permanently operative drainage means,and to tra-p soil particles and prevent outflow thereof with the drainedwater. A

particular object of the invention is to equalize the air pressurebetween the atmosphere and a well receiving water from sunken drains.

In accomplishing these and other objects of the invention I haveprovided improved details of structure, the preferred forms of which areillustrated in the accompanying drawings, wherein:

Fig. 1 is a perspective View partly in section of a drainageconstruction embodying my invention.

Figg2 is a detail central vertical section of a portion of theconstruction including the well head and a Well cover.

Fig. 3 is a detail perspective view of the upper end of the well casing,and portions of tiling connected thereto, and the cover separated fromthe casing and provided with a pressure equalizing tube shownfragmentarily.

Referring in detail to the drawings:

1 designates generally a depressed area such as a low portion of a eld,and 2 the low point of the area. Receiving trenches are dug in spacedrelation with the low point 2, and they are represented intheillustrative application of the invention as comprising a singlecircular trench 3, the low point being the center on which the trenchcircle is formed. All portions of the trench may be of equal depth.Radial ditches 4- are then dug from the trench to the center 2 of thearea, the floors 5 of the ditches inclining downwardly from the floor 6of the trench 3.

A well 7 is then provided at the center of the area, extending to porousstrata 8, and a 1928. Serial No. 275,089.

casing 9 is installed in the well, to receive water conducted by theditches to the cen-` ter of the area. The upper'edge 10 of the casingprojects slightly above the mouth of the well.

Drainage tile 11 are laid on the floor of the circular trench, tocomprise a ring-lilre conduit to intercept and receive water thatmay runtoward the center of the depressed area and water that may fall adjacentthe trench.

Radial tile conduits 12 are installed in the ditches, the outer ends ofthe tile conduits 12 being connected into the circular conduit, and theinner ends extending in notches 13 of the casing for support from thecasing, to receive water from the circular conduit and from the radialditches and conduct it to th well. y

The upper edge 10 of the casing is free, because of the projection abovethe floor of the ditches and the insetting of the radial tile in thenotches. Resting on the edge 10 is a cover 14 comprising a disk-likemember preferably'of concrete, having a central aperture 15 to admit atube 16, which is fixed in the cover, the lower end of the tubeextending into the well and the upper end extending to a substantialdistance above the surface of the surrounding land.

A porous ller 17, for example, gravel, is installed on the tile to fillthe trench and ditches, for filtering soil and other solid particlesfrorn'the water that passes through the channels to the tile.

Drainage apparatus 'of the character described maybe provided ataselected position in relation to a depressed area, for eX- ample, at oneedge thereof, for draining all or a portion of the area. The trench maybe dug in circular form, the circle having a diameter appropriate to thecontour of the land, for example feet; the trench may have a depth of 18inches, and width of 18 inches. rllhe radial ditches have floorsaligning with the floors of the trench at their outer ends, and inclinedownwardlytoward the well, the ditches being, for example, 3 feet deepat their well ends. The concrete cover shields the mouth of the well,and when the porous material deposited, the

air tube assures movement of air from the well, to prevent hindrance offlow of water into the well. The porous material retains the soil forthe area by trapping the soil and checking the velocity of the water,and also prevents clogging of the tile and well by solid particles.

What I claim and desire to secure by Iletters Patent is:

l. In a drainage construction for draining a depressed area, a wellatthe low point of said area, trench portions circumferentially disposedto said well to intercept water flowing toward the well, and radialchannels connecting the well with said trench portions for conductingwater from the trench portions to the well.

2. In a drainage construction, a circular' trench,v a diametrical ditchconnected with the circular trench and having a loor declining towardsthe center on which the circle .is formed, and a well at said center forreceiving water conducted from the circular' trench by the diametricalditch.

.3. In a drainage construction for draining a depressed area,intersecting trenches adapted to contain a porous iiller, a well at theintersection of the trenches7 a cover for the kwell having atube-receiving aperture, and a tube extending into the well and abovethe upper edges of the trenches for equalizing air pressure between theatmosphere and the well. l

4. Drainage apparatus comprising a well including a casing havingnotches in its upper edge, drainage tile disposed circumferentially tothewell, conduits having inner ends seated in said casing notchesconnecting the tile with the well, a coverron the casing, a tubeextending through the cover into the casing, and a porous iller coveringthe cover,

tile and conduits, the tube projecting above the ller to atmosphere. u

5. In a drainage system of the character described for draining adepressed tillable area, ya circular conduit comprising drainage tileadapted to intercept water iiowing over the area, a well at the centeron which the conduit is formed including a casing having its upper endlocated below the conduitV and having notches in its upperedge7 tileconduits connected with said circular conduit and having inner endsresting inthe notches of said casing, a cover seated on the upper end ofthe casing, a tube iXed in the cover and extending into the casing, anda porous filler covering said conduits for retaining soil to conservethe tillable character of the area.

6. In a draining system of the *characterl A described including a tileconduit and a well,

a casing in said well having notches adapted to receive the inner end ofthe conduit and to leave the upper edge of the casing free, a cover``comprising a disk adapted to reston the upper edge of the casing, and atube fixed in the cover having one end adapted to extend into thecasing.

In testimony whereof I aliiX my signature.
